ALARM ACTION FIGURES
Note: Hys in the above figures refers to the Alarm Hysteresis.
AVAILABLE ALARM ACTIONS
NONE None
No action, the remaining Alarm
parameters are not available.
AbHI
Absolute High
(balanced hysteresis)
The alarm energizes when the Process
Value exceeds the alarm value + 1/2 the
hysteresis value.
AbLO
Absolute Low
(balanced hysteresis)
The alarm energizes when the Process
Value falls below the alarm value -1/2 the
hysteresis value.
AuHI
Absolute High
(unbalanced hysteresis)
The alarm energizes when the Process
Value exceeds the alarm value.
AuLO
Absolute Low
(unbalanced hysteresis)
The alarm energizes when the Process
Value falls below the alarm value.
d-HI Deviation High The alarm value tracks the Setpoint value
d-LO Deviation Low The alarm value tracks the Setpoint value
b-IN Band Acting (inside) The alarm value tracks the Setpoint value
b-ot Band Acting (outside) The alarm value tracks the Setpoint value
